Title
(EN) SHAFT EXTRACTION PREVENTION STRUCTURE OF CONSTANT VELOCITY JOINT
(FR) STRUCTURE DE PREVENTION D’EXTRACTION D’ARBRE D’UN JOINT A VITESSE CONSTANTE
(JA) 等速ジョイントのシャフト抜け防止構造
Abstract
(EN)
A shaft extraction prevention structure of a constant velocity joint capable of solving a problem in such a conventional structure where a shaft is joined to an inner ring at low cost wherein a structure which can be easily disassembled and a structure which cannot be easily disassembled can not be selected. Where the angle of the shaft end face side wall of a retainer ring groove in the shaft is &agr; and the angle of a contact part formed on the inner ring is &bgr;, a relation between these angles is set to 0° < &agr; ≤ &bgr;, and the shaft and the inner ring are assembled in combination with each other according to specification requirements.

Structure de prévention d’extraction d’arbre d’un joint à vitesse constante susceptible de résoudre un problème dans une telle structure conventionnelle où un arbre est relié à une bague interne à faible coût, selon laquelle une structure qui peut être facilement désassemblée et une structure qui ne peut pas être facilement désassemblée ne peuvent pas être sélectionnées. Quand l’angle de la paroi latérale avant de l’arbre d’une rainure de bague de retenue dans l’arbre vaut &agr; et l’angle d’une partie de contact formée sur la bague interne vaut &bgr;, une relation entre ces angles est définie par 0° < &agr; ≤ &bgr;, et l’arbre et la bague interne sont assemblés en combinaison l’un avec l’autre selon des exigences de la spécification.
